my question is - did i use the command ORDER BY DECODE properly? because when i executed the said script no error was generated. the requirement was - i have to sort the data based on the specified fields. if this is single field only -> no problem, but it requires more than one field. could anyone help me?

thanx

If you don't know the answer why do you expect any of us to know the answer?
We don't know the requirements.
We don't know the data.
We don't know what were the results.

Congratulations

>but it requires more than one field.
What requires more than 1 field?

>could anyone help me?
Help you with what exactly?
I, for 1, don't know what is wrong or what would be the correct or desired results.

I very much doubt that you have used DECODE correctly in the Order by.
The decode statement:
decode('Delivery Date',
'Tool Number/Driving Task ID',tail_no||part_number||task_cd, 
'Driving Task ID/Tool Number',tail_no||task_cd||part_number, 
'Delivery Date',tail_no||delivery_date, 
'Work Order Number',tail_no||work_order, 
'HM Facility Location',loc_list.loc_cd||loc_list.loc_name||tail_no,' ') 
will always return
tail_no||delivery_date.

You should make the first parameter in the decode statement a variable, not a constant.
